To estimate the number of missed trauma deaths and high-risk patients using 3 commonly-available sources of trauma data (including trauma registries), compared to a population-based sample. We also assessed the magnitude of bias for field triage accuracy metrics (sensitivity and specificity) when calculated with different data sources.

Impact Statement:

Large blind spots exist in the evaluation of trauma systems – this study seeks to quantify and characterize these blind spots.
